Stick with Vivienne. It's so much prettier. I love that name, I had it on our list until DH nixed it. JudeAndre is very nice as well. Adrien and Gabriel are both nice names, though I'm not sure about them in that order.
Not a huge fan of Demetria, though I do like Simone. Demetria seems really dark to me.WhitneyGrace I have a bias against because I have a sister named Whitney that I don't get along well with, so I shouldn't give an opinion there. Good luck with your list!
